New Product: SDP101 Power Modules

Do you have an application with a TO-220 linear regulator that you’d like to replace with a switching power supply for improved efficiency?

The SDP101 series power modules are now available starting with the 3.3V output device. These modules feature a simple three-pin design (VIN, GND, VOUT) and are compatible with most TO-220 linear regulators. With a max operational input voltage of 5.5V and standard fixed outputs of 3.3V, 2.5V, 1.8V, 1.2V, and 1.0V these will surely find quick use in the lab or in your next product. Custom fixed voltages available upon request.

Time-of-Flight Laser Distance Sensor, PMOD Compatible

Available for sale on Tindie!

Shield Digital Design is proud to announce our latest product: the PMOD compatible Time-of-Flight Laser Distance Sensor based on the ST Micro VL53L0X. The sensor has a range of up to 2m, and included both the right-angle header as well as straight header for flexible use. (The VL53L0X is mounted to the bottom of the board such that it would face away from the development board when used with a straight header). The 6-Pin PMOD interface includes the I2C bus, shutdown, and an interrupt output.

Schematic is available here: TOF_Ranging_Sensor_Kicad.

Please contact me for information about how to purchase!  (Thanks to for the software I use to test these devices)

You might have noticed that VCC and GND are swapped on the photos of the device… the files for the prototype run erroneously flipped the pins on the schematic, but the correct pinout was used for the production devices.
